Specific embodiment
Feature of the invention and other correlated characteristics are described in further detail by embodiment below in conjunction with attached drawing, with
Convenient for the understanding of technical staff of the same trade:
Such as Fig. 1-6, label 1-15 is respectively as follows: adjustment cushion block 1, calibrating installation 2, guide cone clamp 3, direction regulator 4, angle in figure
Steel 5, embedded bar 6, prefabricated stand column 7, embedded sleeve barrel 8, bracket 9, jacking apparatus 10, cushion cap 11, clamp handle 12, connecting shaft 13, pincers
Mouth 14, guide part 15.
Embodiment: as shown, the present embodiment is specifically related to the construction of a kind of prefabricated stand column quick device to hole and pose adjustment
Method, the construction method by before the embedded bar 6 on the 8 device to hole cushion cap 11 of embedded sleeve barrel of 7 bottom of prefabricated stand column just holding
The leveling of 11 elevation of top surface of platform, makes the embedded sleeve barrel 8 of prefabricated stand column 7 during lifting by homemade guide cone clamp 3
In embedded bar 6 on rapid device to hole cushion cap 11, then by the plan-position of the adjustment prefabricated stand column 7 of direction regulator 4, pass through
Jack prefabricated stand column 7 on bracket 9, adjust prefabricated stand column 7 verticality, whole process time-consuming is short, noise is small, it is easy to operate simultaneously
And reduce the security risk in hoisting process.
As shown in figures 1 to 6, the quick device to hole of one of the present embodiment prefabricated stand column and the construction method of pose adjustment include
Following steps:
(1) pre-production prefabricated stand column 7, the prefabrication phase embedded sleeve barrel 8 vertically arranged in the pre-buried circle in 7 bottom of prefabricated stand column,
Injected hole is opened up in each side of prefabricated stand column 7, so that injected hole is connected with embedded sleeve barrel 8, to facilitate into embedded sleeve barrel 8
Slip casting, injected hole can also be replaced with pre-buried screw shell, and corresponding screw shell runs through embedded sleeve barrel 8, while screw shell
One end to stretch out in corresponding side；Prefabricated cushion cap 11, and corresponded at 7 drop-off positions of prefabricated stand column in the Mosaic face of cushion cap 11
The setting form of vertically arranged several embedded bars 6, embedded bar 6 is corresponding with embedded sleeve barrel 8, and the diameter of embedded bar 6
Less than the internal diameter of embedded sleeve barrel 8, to ensure that embedded bar 6 can protrude into embedded sleeve barrel 8.For embedded sleeve barrel 8 and embedded bar 6
Laying form, can require be changed according to Practical Project, such as two circle of setting or multi-turn embedded sleeve barrel 8 and embedded bar 6,
It can be laid in the form of circle, triangle etc..
(2) pacify by the injected hole of the embedded sleeve barrel 8 positioned at each center side position inside connection prefabricated stand column 7
Bracket 9 is filled, i.e. a bracket 9 is respectively installed in slip casting hole site in the four of prefabricated stand column 7 side；Cushion cap 11 Mosaic face (i.e.
Top surface) four sides be arranged angle steel 5, every one side 5 medium position of angle steel be arranged direction regulator 4；Spelling is drawn on cushion cap 11
The central axes of the four edges of junction, and it is mutual on four central axes of the Mosaic face of cushion cap 11 arbitrarily to place two decorating positions
Vertical calibrating installation 2, while the line of ink marker on bullet on the vertical middle line of four sides of prefabricated stand column 7；In the present embodiment, calibration
Device 2 can be theodolite or total station.
(3) measure the altitude data of the Mosaic face center of cushion cap 11 with level, and with the setting on design drawing
Value is compared, and places certain thickness adjustment cushion block 1 by the Mosaic face center in cushion cap 11 to adjust the splicing of cushion cap 11
The elevation in face, to meet design requirement, adjustment cushion block 1 can be steel plate and be also possible to rubber slab.
(4) it lifts by crane prefabricated stand column 7 and is transferred to the top of cushion cap 11, clamp cushion cap with two homemade guide cone clamps 3
Two embedded bars 6 on 11, general this two embedded bars 6 clamped of choosing are located at not ipsilateral, prefabricated stand column 7 gradually under
It falls, since guide cone clamp 3 has vertically arranged guide part 15, therefore bootable prefabricated stand column 7 is pressed both along guide cone clamp 3
Determine direction whereabouts, the embedded bar 6 on the successful device to hole cushion cap 11 of embedded sleeve barrel 8 in final prefabricated stand column 7, when embedded sleeve barrel 8
Part is when covering outside precast reinforced 6 upper end, guide cone clamp 3 can be unclamped and guide cone clamp is displaced downwardly to be detached from it is pre-buried
Thus sleeve 8 can smoothly be taken from guide cone clamp 3.The diameter of embedded sleeve barrel 8 is greater than guide cone clamp 3 and clamps embedded bar 6
When outer diameter.
Guide cone clamp 3 in the present embodiment includes clamp handle 12, connecting shaft 13 and plier 14, and clamp handle 12 passes through connecting shaft
13 are connected with plier 14, and when forcing in clamp handle 12 moves toward one another it, plier 14 will be realized and is engaged, and plier 14 is stung perpendicular to it
Guide part 15 is provided on conjunction face, guide part 15 is tapered, and plier 14 and guide part 15 can be integrated molding, is also possible to point
Section welding is formed.
(5) continuation of prefabricated stand column 7 is gradually fallen under the guiding of embedded bar 6, is fallen to prefabricated stand column 7 away from cushion cap face
When 3-5 centimetres of height, side bottom edge center (i.e. side line of ink marker center line and the bottom of prefabricated stand column 7 are observed by calibrating installation 2
The intersection point on side) and the corresponding sides on the Mosaic face of cushion cap 11 central axes deviation, then utilized according to the deviation data that measures
The horizontal jacking prefabricated stand column 7 of direction regulator 4 being arranged on angle steel 5 at four sides of cushion cap 11, since prefabricated stand column 7 is at this time
Suspended state, therefore jacking operation is relatively easy to, so as to adjust the plan-position of prefabricated stand column 7, then again slowly under hang it is prefabricated vertical
Column 7 makes it accurately fall on the Mosaic face center setting position of cushion cap 11；Direction regulator 4 can be can precession major diameter spiral shell
Bolt is also possible to the equipment such as jack.
(6) after prefabricated stand column 7 is fallen on down on cushion cap 11 completely, the side top margin of prefabricated stand column 7 is observed using calibrating installation 2
The deviation of the central axes of the Mosaic face of center (i.e. the intersection point of side line of ink marker center line and top margin) and cushion cap 11, then basis measures
Deviation data using cushion cap 11 Mosaic face surrounding jacking apparatus 10 jack prefabricated stand column 7 side on bracket 9, thus
The verticality of accurate adjustment prefabricated stand column 7, jacking apparatus 10 can be the equipment such as jack.
(7) subsequent pouring construction is finally completed the splicing of prefabricated stand column.
The beneficial effect of the present embodiment is: (1) package unit used in is simple, safety, practical, energy during lifting
Keep column quickly in place, reduces number and time that hoisting process pilot scale is hung；(2) in prefabricated stand column bottom sleeves device to hole cushion cap
Just cushion cap face elevation is leveled before embedded bar, can be clamped by self-control guiding taper so that column bottom set during lifting
In the rapid device to hole cushion cap reinforcing bar of cylinder, and the plan-position of column can be adjusted by direction regulator, it can also be prefabricated by jacking
Bracket on column, the verticality of adjusting post；(3) whole process time-consuming is short, noise is small, easy to operate and reduce lifting
Security risk in the process.
